Hello. I'm currently working with the TLSR8273 with the BLE stack and I have created a custom application on a multiprocessor platform. Everything is working correctly but now my next step is to update the BLE application from the main MCU. The only communication port available between the main MCU and the BLE chip is the Uart.

I have worked on serial bootloaders for BLE before but I really would like to update only the application, since there is no need to update the BLE stack because it never changes.

Is there some code or application note I can follow to create or migrate a serial application bootloader?

Thanks in advance.
